GAS APPARATUS.

QIPECIFICATION forming part of Letters Patent No. 312,481, dated February 17, 1885.

Appicaiion filed September 20, 1984. (No model.)

To 'all'whom it may concern.-

Be it known that I, WILLIE M. Gasman, of Columbia City, in the county of Whitley and State of Indiana, have invented certain new and useful Improvements in Gas Apparatus; and I do hereby declare that the fol lowing is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which fornta part of this specification, and in which Figure 1 is a perspective view of a coal-gas bench for the manufacture of illuminating- Fig. 2 is a perspective view of one of the retorts of the same, with a portion broken away for the purpose of showing its interior construction. Fig. 3 is alongit-udinal vertical sectional view of the purifier, and Fig. 4 is a detail view in perspective of the scouring disks or diaphragms detached from the purifier.

The same letters refer to the same parts in all the figures.

carbon is introduced into the retorts from a suitable receptacle through pipes having suitable back-pressure valves; and it consists in the improved construction and combination of parts of such an apparatus in which the en riched gas is purified by passing it through areceptacle containing salt and various absorbing materials, as hereinafter more fully de scribed and claimed.

In the drawings hereto annexed, A designates the coal gas bench to which my invert tion is applied, and which is, in the main, of ordinary construction, provided with the retorts B B, the front ends of which have tightly-fittipg doors 0 0, adapted to be tightly closed and retained by screw-clamps D D, of suitable construction. The front ends of the retorts are provided with upwardly extending pipes E E, connected by a pipe, F, which conveys the products from the retorts to a hydraulic tank, G, suitably located and partly filled with water. ThepipeF extends nearly to the bottom of the tank G,in which a waterseal is thus formed. Another pipe, H, conveys the gas from the tank G to the purifier I, which will be presently more fully described.

J designates a pipe throughiwhich any suitable hydrocarbon is conveyed from a suitablylocated reservoir to atransverse pipe, K, provided with cocks or faucets L L, located above the oil-cups N N, mounted upon pipes 00, provided with back-pressure valves P P. The pipes O, of which there is one for each retort, extend downwardly, and are bent, so as to form traps Q, from which the said pipes extend upwardly into and horizontally through the retorts, so as to discharge the hydrocarbon upon thehot coal charges contained in the latter. It will be seen that the fiow of oil may be readily controlled and regulated.

The purifier I consists of a cylindrical tank or vessel having a detach able head, R, to which a pipe, S, is connected, through whichthe gas is conveyed from the hydraulic can into the said purifier. The opposite end of the latter is provided with an exit -pipe, T, through which the gas may be conducted to a storage chamber or reservoir.

The purifyingtank is provided with a central longitudinal rod, U, upon which may be placed a series of neatly-fitting perforated disks or diaphragms, V V, between which keeping them suitable distances apart. Between the disks or diaphragms throughout the length of the purifyingcylinder is placed a packing consisting of a mixture ofsalt and iron filings, or sawdust and iron filings, or salt and sawdust and iron filings combined, the purifying qualities of which will coact with the scrubbing properties of the perforated diaph'ragins to purify and increase the illuminating-power of the gas passing through the cylinder. A grate and ash-pit, with a suitable fire-door. are constructed in the usual manner under the retorts, for the purpose of heating the charges placed in the latter.

By this invention all the olefiant gas con tained in coal may be utilized and enriched to any desired illuminatingpower by carbureting the same while in the retorts by the direct influx of hydrocarbon oil. The products pass from the retorts through the tank G directly to and through the purifier, where they so washers \V are interposed for the purpose of filter through the mixture placed between the scrubbing disks or diaphragms. This mixture or compound takes up all the sulphureted hydrogen with which the gas is tainted. The sulphur will remain as a salt in the compound, while the ammoniacal tar is condensed and caught in a drip, or permitted to run back into the hydraulic can, above which, when circumstances will permit, I prefer to suspend the purifying-cylinder vertically. \Vhen the gas issues from the purifier, it is entirely free from any of the ammoniacal and sulphur compounds. The packing material in the purifying-cylinder, with exception of the salt, requires onlyto be taken out occasionally and aired and dried, when it may be used over again, the sulphureted hydrogen being caused to evaporate. Salt is to be supplied or added as required.

My improved process, it will be observed, is continuous, and the apparatus required is simple and inexpensive.

I am aware that it is not new to enrich gas by introducing hydrocarbon into the retort in which the gas is produced, and I am also aware that apparatus for purifying gas has been made where the gas is carried through a receptacle filled with sawdust and iron filings, and I do not claim such constructions, broadly; but

I claim 1. In a purifier for gas, the combination of a cylindrical vessel provided at its ends with an inlet and an outlet pipe, a number ofspaced and perforated diaphragms placed within the vessel, and a packing of sawdust, iron filings, and salt interposed in layers between the said diaphragms, as and for the purpose shown and set forth.

2. The combination of the retorts, oil-supply pipes entering the same, and provided with bends or traps and with back-pressure valves, the exit-pipes connecting the retorts with a tank having a watenseal, an d the pn rifier consisting of a tank provided with perforated diaphragms, between which is interposed a packing of sawdust, iron filings, and salt, the whole arranged and operating substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
